(Flutter/Dart-PDF) How to handle long text in a Multipage Table without causing InstanceOfTooManyPages error?

Question

I have a text that is so long that it spans several pages. Since it is in a table that also spans multiple pages, the TooManyPages error is thrown.

This is the code as a Table and Paragraph. Please help me to make the text span multiple pages.

            }
          }),
        ],
      ),
    ],
  ));

If the text is shorter than a page, my code works.

I tried, paragraph, text, Wraps and so on. I even converted everything to containers and rows and the same error is thrown.
